"Lingvo devas esti ne celo sed rimedo."

Translation: Language must not be a goal but a means.

[A.LeanderH]

Is "... devas ne esti..." also acceptable or no?

[realfoodman]

I think that would make the "ne" apply to both goal and means, which is not what is meant.

[Jaerivus]

I think you would want to arrange it: "Lingvo ne devas esti celo", in which case you'd be articulating that "language doesn't have to be a goal."

Or so say I, the lowly pupil.

[Jones_Rick]

How does one say: language has not to be a goal but a means.

[Cocio_16]

eble : « lingvo ne devas esti celo sed rimedo » ?

[vgSe5]

Could be hard to apply it in Esperanto

[KubaWorlap]

The goal is easier communication. The means is a simple language.

[Jaerivus]

Personally, on Duolingo, Esperanto is assuredly my goal. I must be a disappointment to the developers.
